Abstract
In accordance with the present invention, progressive changes in amplitude as a function of offset of common gathers can be more easily identified by displaying difference envelopes of 'near' and 'far' amplitude vs. time traces of each gather, as a function of common groups of centerpoints. A significant--and progressive--change in P-wave reflection coefficient as a function of the angle of incidence (within sections) indicates valuable characteristics, such as hydrocarbon-bearing potential and/or lithology of the reflecting horizon.
